"I will disguise it as an exotic bird. Should pass unnoticed."

"Fantastic."

And then there are still four days in this lightleaper. Maitimo and Findekáno both separately consider that perhaps they didn't think this through.

Well, there are rooms and all the computer-translated reading material about Canal Country they could want.

That will occupy them!

And eventually here is galaxy, and Cam does more binary search to find the planet, and then they have another five days!

Well, there's plenty of reading material. "Oooh," Findekáno says on the third day. "It's really a shame they aren't chipped. Their magic runs off working memory; if we could give them a necklace they'd have immortality on the spot, I think, and lots of other stuff they have but can't remember."

"Oh damn. Well, that's a reason to look into supplying thought-collectors to people who aren't natural-born cyborgs, I guess..."

"Lots of Men have asked at home," he says, "there's just no way at all to safely experiment even if an instance of Feanáro's figured out how the thought-collection even works."

"I think one has," Maitimo says. "One might be able to get some of the benefits of blessings without the thought-collection use of the chips, too. But it's at least a few years out. That's a hard problem."

"You could somewhat test on daeva. The indestructibility's confounding but when we're trying to let stuff work it works on us like humans. Or, probably 'source species', don't know about daeva Dwarves."

"I'll suggest it," Maitimo says. 

"I wonder if people who aren't from here can learn their magic."

"You probably can't make animals smart enough for us to try to bind them into familiars," Findekáno says, "and I think they're usually assigned at - birth? But maybe they needn't be..."

"Or maybe you can borrow somebody else's or something?"

"Perhaps we can ask the local royals, if they seem generally competent. They probably won't hesitate just because Findekáno and I would be ludicrously powerful in the local system, you exist and are ludicrously powerful with or without the local magic. Wonder if you could make your familiar part of yourself for the purposes of indestructibility, since untranslateable bad thing happens when they're killed..."

"Yeah, that would be a thing I'd want to check, I'd rather not have any untranslateable bad things happen to me. I have no idea how to expect that to work with backups either."

"At a minimum it seems vanishingly unlikely to affect other instances, so I think I'd take the chance."

"It might, we can't know for sure, but it does seem implausible."

"And unless I'm much misunderstanding how this works we'd have human immortality an hour after pulling it off," Findekáno says. "I think the chance is easily worth taking."

"Sure, I wouldn't stop you."

He raises an eyebrow. "On this occasion I did not particularly fear it. if you disagree with the cost-benefit evaluation I'd want to talk it through anyway."

"...that's. Not what I meant. I would not consider it unreasonable for someone to volunteer to take the risk, is what I meant."

He nods. "It might not work anyway. I'm confused by how magical interactions among worlds work in general - ours doesn't seem to have native magic, unless the Ainur themselves were. Summoning as far as you know was initially exclusive to yours, and it worked in Arda only once Valinor was destroyed - were the Valar suppressing it? Did they introduce a loophole when they tried to ban it which unraveled when they were murdered?"

Could you not, Maitimo says to him.

Noted. "I would have expected magic to go by universe, not species, like the law of physics, but that's not what it looks like it's doing."

"Well, daeva magic goes by species. ...I may have completely forgotten to mention parlor tricks to anyone."

"I think you might have," Maitimo says. "Parlor tricks?"

"Humans from my world can do little tiny stupid magic. It is virtually never the best way to accomplish anything, and it can only accomplish very small versions of the things daeva can do - I think the standard use case besides, well, doing a parlor trick to show off that you've mastered one, is to push buttons on assistive devices if you're too paralyzed to do anything else. Sometimes somebody writes a novel where Our Hero is tied up and has to complete a summoning circle by parlor trick or something but it just never comes up in reality like that."
